This invention relates yto a gas heater. An object of the invention istofprovide a simpleand Veiiicient construction of gas Yheater whereby amaximumamount of heat can be deflectedand radiated and circulated'for agiven consumption of gas.

Another .Objest @caceres the Prevson 0f Simple and efficient meets.whereby theses used fer'heatns @au be preheated in e Smple manner beforebeing burned.

A further object concerns the provision of simple and eiiicient meanswhereby the heat issuing from vtlw'burller @en be directed' mosteciently into the lower portion of the rQQm- A still hfurther objectconcerns the provision of simple and eficient means whereby theconstruction is'composed of a minimum number of simple and rdurableparts which canbe readily assembled and disassembled.

The invention is illustrated in the drawings, .of -Whihf Y -Fgure l Visa front elevation of the device;

The term of the preheating through a portion of the the .invention Shownn the drawings is a preferred form, although itis "understeod thatmodifications in the, construction and arrangement of the parts and inthe character of the materials used may be adoptedwithout departing fromthe spirit of the llVeIltOIl 1215 S013 flth .in the appended claims. o YA o o o, The general l idea pO ,the invention involves the .provisionlof a deep reflectoricasing having curved walls within wh-chone or moregas heating devices arelocated. o The ,casing 'isvprovided with a screenacross its upper`V forward open end for thepurpose of pro tecting theclothing andV 'parts of the bodyfrom coming in contact with the heater,otherwise .the casing is entirely open. Near the burners proper, withinthe casing, ya coil of piping isk disposed for the purpose of passingthe gas therethrough before .reaching the burner, so as Itopreliminarily heat it.` Each .burner ,prope r comprises a hollow ringforming va gas chamber having a plulrality of rowsof Vapertures in itsupper sur- I faoejhrough which the gas Yescapes and is ignited.` Above-burner ring disposed L a mantle which is somewhat bell-,shaped ybutof'''conside'rably.y larger ldiam'eter than; the

ring7 l to `provide ja' combustion chamber; to"

air isintroduced. by the' suction yaction of the gas Jets." The',uppe'surface o'f thisV mantle 1s "apertured topermit't 1e llame 'to'pass"ther'eout.V Over the Vtop of this mantle isv a lhood which isVadapted to. trap any un-Y burned gas andto deflect lthe heat and flamedownward along theouter s'urfacefof the mantle.V` Thefmantle'and thehood are mounted on av single threaded stem support# ed from the burnerring.v At t'helto'pf'of-thev` stem above ythe hood and the mantle isdisposed a reflector plate,4 somewhat'c'urved concave downwardly,adaptedto spread the heat out. and distributeity more uniformly firstinto the lower portion of the room.

The 'burner` ring .issupplied with gas through a conduit to whichsuitable'riozzles are connected, lpreferably at an;` angle,l thesenozzles being connected totheend ofthe conwhich is provided withairinlet adjusting means. o

ln the preferred form of the invention shown in the drawings, I providea deep casing l having curved` forwardly extending walls such as-2 anda's'creen 3, preferably of'wire. `Withinthe casing there-are `aplurality of burners, each of which'comlsusV prises a hollowburner-ringe.within'whichl a gas chamber is formed. A crossbar 5 isconnectedV integrally to the burnerl ring and supports a threaded stem no The upper surface vofthe burner ringis provided with a pluralityof'row's of aperf tures Z and 8 through vwhich the gals escapes. l

Abovethe burner ring is located a mantle 9, preferably bell shape,v andof considerably larger diameter at its lower edge than the burner ring.The luppery surfacel of this man'- -tle is perforated as at 10 to permitthe gas'and the flame to escape. On the stemA above the mantle 9 islocateda hood l1, somewhat bell-shaped and adapted' to receive anyunburned gas to complete its combustion and to directthe heat and flamedownward along the outer surface of the mantle 9.

On the stem 6` above 'the -hood .11 is a: v reflector plate 12 Vofshallow configuration,

more effectively; y c

. The burner ring J4 1s connected by a con-r dulbl .t0 ,an alf chamber.le harms ,means 17.05` c'oncaved downwardly', and adapted to spread theheat out into the ,lower part of the room v Y such as for adjusting theadmission of air. Gras nozzles 16 are connected to the end of theconduit at an angle so that the gas will enter the conduit in adirection moving forwardly and upwardly, which; is found to moreeffectivelyv project it into theburner ring and to do away with theliability ofY leakage. Each nozzle, and there may be several, isconnected to a conduit 17 leading to aV coil 18 disposed within thecasing 1 near the burner ring a, so that the gas is prehminarily heatedbefore it gets to the nozzle. By

reason of the fact that the burners are placed vvwell forward'within thedeep casing, there is formed a chamber back of the burners and betweenthem and the rear wall of the casing which acts as a heating chamber.The circulation of air, as indicated by the arrows, will naturallyresult in Vthe air passing up ynot only through the burners but back ofthe admission `adjusting means is regulated and4 the nozzles are opened,the gas issuing from the burner ring being ignited by suitable Ll i)means, the mantle 9 and the hoodvll become Vincandescent,'the flame andheat spreading out and causing a suction of air up through the front ofthe casing, as shown by the arrows inFig. 2, and past the burner. Someofthe air goes under the mantle Y9 and assists in .burning the gas. willget in beneath the hood 11 to complete the combustion. The heated airwill rise and strike the plate 12 and be spread out uniformly into theroom.. It is foundV that this device is eXtrem-ely eflicientin theconsumption of gas and'in the generation of heat as well as inthedistribution .of it.
